Phantom Chest inside Real Chest

When I load the game up, the chests look normal, but after awhile, whenever I open a chest, the lid of the chest appears both open and closed. I can still use the real chest normally. If I pick up the chest, a phantom chest is sitting in the original chests place. I cannot interact with the phantom, and if I leave the area for awhile, it disappears. This was happening in 32d and is happening in 33a.
